Investigation: 20 How much cobalt is in the soil? Introduction: By completion of investigation 20‚ a standard curve of absorbance versus known cobalt (II) nitrate was prepared. The concentration of cobalt (II) ion obtained from a soil sample was determined. Whether or not cobalt nitrate should be added to the soil was determined. If cobalt nitrate needs to be added‚ then how much will it be required to meet the necessary nutritional needs of the animals was established. In colorimetry

Design: Investigation of Fermentation Introduction Introduction Yeast (Saccharomyces)is a single-celled microorganism in the Fungi family. It anaerobically respires sugars to produce ATP‚ as well as the waste products ethanol and carbon dioxide gas. This process is known as fermentation. There are various factors that affect the rate at which yeast respires. Aim To investigate the effect of concentration of table salt (sodium chloride) on the rate of fermentation of sucrose using yeast‚ measured
